Bug#668437: lintian: Identify -dbg packages that have binaries with no debugging symbols



Package: lintian
Version: 2.5.6
Severity: wishlist

Hi!

Using #652099 as an example, we have a source package that has a -dbg
binary package, with files located under /usr/lib/debug/ as they should
be but with one problem: there are no debugging symbols.

Could lintian do a new check against the binaries in a -dbg package to
see if they indeed have the proper debugging symbols?

Something like doing a "nm -a $file | cut -b 18" and grepping for "N"
If no N is found then we have a file with missing symbols and a warning
about this.

(I don't know if nm + cut + grep is the best way to test for debugging symbols, but
it seems to do the job)

Thank you!

Best regards,
Nelson
